Chemistry Final Exam (Answered) Oxidation Rules Rule 1: The oxidation number of an element in its free state = 0 (Also true for diatomic elements) -Mg=0,H2=0, C=0 Rule 2: The oxidation number of a monatomic (one-atom) ion is the same as the charge on the ion -Mg^2+=+2, Na^+=+1, O^2-=-2 Rule 3: The sum of all oxidation numbers in a neutral compound is zero. The sum of all oxidation numbers in a polyatomic (many-atom) ion is equal to the charge on the ion. Rule 4: The oxidation numb...

Chemistry: Final Exam Review 2023 with complete solution How many valence electrons are in an atom of chlorine? 7 How many valence electrons does aluminum have? 3 Define Reaction Rate The decrease in concentration of reactants or the increase in concentration of products with time. How does increasing temperature affect the rate of reaction? Increasing temperature causes the kinetic energy to increase. Thus, molecules are moving faster and colliding more frequently. This causes the rat...

Our objective is to identify the functional groups present in an organic compound through;  Tests for Unsaturation  Tests for Alcoholic Group  Tests for Phenolic Group  Tests for Aldehydic and Ketonic Groups  Tests for Carboxylic Groups  Tests for Amino group

Organic Chemistry: Organic chemistry primarily deals with the study of compounds that contain carbon atoms bonded to hydrogen, oxygen, nitrogen, sulfur, and other nonmetals. It focuses on carbon-containing compounds, including hydrocarbons (such as alkanes, alkenes, and alkynes), as well as functional groups like alcohols, acids, and esters. Organic chemistry often explores the behavior of compounds found in living organisms, including proteins, carbohydrates, and DNA. It is crucial in the...
